No reormr, .amc1t1zen:otlthe United States, residing at Homm'in theaeounty oi deii'ersonsand State or? lihsconsm, have invented arnew sanduseitul Attachment for CornPlanter-ain't which i'thc ftollowi'n g is. a specification.

This invention relates to an attachment "tor corn planters, by means of which a measured quantity 01 other seed, as 'cfor example soy beans, may be planted along with :the corn.

Figure his a sectional view on the line o6 of Figure 5.

The auxiliary seed receptacle 18, which may contain soy beans, pumpkin seed, or any other seed which it may be desired to plant with the corn, is secured to a supporting bracket 19 provided with depending arms 20, which are formed with slots 21 at their lower ends, or with any other suitable means by which. they may be supported for vertical adjustn'ient on a yoke 22 secured to the tongue 13, or any other suitable part oi the planter frame. Suitable bearings 23 are also secured to the bracket 19, and rotatably support a feed roll shaft 2-1 adapted to be driven by any suitable means, as for example, a sprocket wheel 25, connected to suitable gearing on the feed shaft of the planter.

The mechanism for feeding the seed from the receptacle 18 includes a feed roll 28 se cured to the shaft 24 underneath the receptacle, and surrounded by a housing 29 vsaid opening and substantially closes :seed 7 into two streams.

secured tooififormingaspart oi' thebracket 19. Asuitable openlng 30'is formediinthe bottom or the receptacle 18, through which :the seed is dropped into contact -Wltl'l the roll 28. The roll :is located directly below the same.

Provision is also :made' for separating the For this purpose the housing is-divided into .two compartments 'Jbya flange 31, and the il'Oll is provided with two spaced series of substantially elliptical shaped cir eumierential cups or recesses 32, which travel underneath guiding flanges 33,

spective compartments from which they are discharged through-the openings, 34.. The channelsia'reformed by striking up or:raising the bottom of the receptacle at one side of ."the opening 30 in alinement with the recesses provided in t'he roll,lthe openends of the channels facing the roll and being substantially Nertical. The channels have perpendicular :side walls and an inclined top wall, which is tangential to the roll and overhangs the latter, This construction provides exits from the re'ce ptacle for the seed, which, when the recesses in the 8 roll, by therot'atable anovenient of the latter,"come in vertical alinement with the channels, a'llowsithe'seeds to pass out. That portion ofthe side of the opening 30 between th'e ic hannels fits t'h'e'roll rather closely :so that the seeds cannot escape except thi 'ough the chamils. By this means, the

seed is prevented from getting between the roll and the housing and clogging the roll, and at the same time exit passages are provided which are tangential to the periphery of the roll and cooperate with the recesses 32 to deliver the seed without crushing. The sides of the cups or recesses 32 have a gradual outward slope, as shown at 85, so that beans which do not go through the channels 33 will. slide ofl' without being crushed, and there is no chance for them to wedge or clog. Nipples 36 extend downwardly and forwardly from the openings 34:, and may be connected by flexible hose 37 to the corn planter shoes.

It will be particularly noted that the at tachment is of simple and inexpensive construction, and yet has a Wide range of adaptability, so that it may be attached to any style of corn planter, and only one ill ill

stock size need be made. The rate of feed may be adjusted by changing the ratio of the gearing, or by changing the roll 28 for one having a greater or less number or" reeesses 32.

The cooperation between theu'ecesses 32 in the feed roll and the channels 33 will be clear from the following explanation. It the recesses 32 were made deep enough so that some of the beans could pass throu h, without the overhanging channels 33, some of the beans which projected a little above the recesses would be crushed. I'tthe sides of the recesses were perpendicular to the axis of the roll, some of the beans would get wedged in so that they would not fall out. hen the center of the recess is under the mouth of the channel it makes the opening longer, and when the edge of the recess is at the mouth of the channel, the opening is smaller, but still large enough so that a bean may pass through. No matter how deep the recesses might be made, it the channels were not used, some of the beans would be crushed and stick in the openin It is the action of the recesses in enlarging and diminishing the size 01" the opening which causes the beans to be fed without crushing or clogging.

lVhile I have shown specifically one adaptation of the invention, it is to be understood that this is merely illustrative, and that modifications may be made in the details of construction and the relative size and arrangement of the various parts thereof without departing from the spirit of the invention as defined in the claims.

What is claimed is:

1. A receptacle with an opening in its bottom, a feed roll fitted into said opening and having a series of circumferential recesses, a housing surrounding the lower part of the roll and having a discharge opening, the opening in the receptacle bottom being raised on one side of the opening in alinement with the recesses to form a restricted exit for seeds carried in the recesses.

2. A receptacle with an opening in its bottom, a feed roll beneath said opening and substantially closing the same and having a series of circumferential recesses, a housing surrounding the lower part of the roll and having a discharge opening, a guiding channel overhanging the roll at one side of the opening in the bottom of the receptacle and formed by a raised portion of said bottom tangential to the roll, said channel being in alinement with the recesses and cooperating therewith to discharge the seed without crushing.

A receptacle with an opening in its bottom, a feed roll located beneath said opening and fitting the same, said roll hav ing two spaced series of circumferential rccesses, and spaced channels overhanging the roll and formed by raised portions of the receptacle bottom at one side of said opening and tangential to the roll, said raised portions being in alinement with the said recesses and cooperating therewith to discharge the seed without crushing.

4. An attachment for planters, comprising a receptacle provided with an opening in its bottom, a feed roll mounted for rotatable movement beneath said opening, said roll having a series of circumterentially spaced shallow recesses forming cups, which are substantially elliptical in shape and have a gradual outward slope toward the sides, and a guide channel formed at the bottom of the receptacle above the recesses of said roll, saidchannel having perpendicular side walls and an inclined top wall, said guide channel providing a passageway which cooperates with the recesses in the roll to discharge the seed without crushing.

In testimony, that I claim the foregoing as my own, I have hereto affixed my signature. LEONARD G. NOTBOHM.
